From b37f7e0160ae30d75c939bcd1aab8df3a2178820 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Thu, 3 Oct 2013 19:36:03 -0700 Subject: i965: Add a note about the late-allocation in intel_bufferobj_buffer(). This was mostly for the i915 system-memory VBO code, which we don't have any more, but since that existed we've ended up producing dependencies on it being there.
